Cheryl Shepherd, the mother of KC Chiefs linebacker Jovan Belcher allegedly told police her son argued with his girlfriend Kasandra Perkins over their daughter’s paternity before he shot her multiple times and killed her, before killing himself.

Shepherd was present in their home when her son killed Perkins. According to the New York Post, she told investigators her son was questioning if he was the biological father of their 3-month-old named Zoey.

The Post reported a Kansas City law-enforcement source and another source close to the case both confirmed, “there was a question about the paternity.”

However, Friday morning the spokesman for the Kansas City police denied the Post’s report saying it was inaccurate after completing their investigation of the murder-suicide.

The spokesman, Darin Snapp, said in regards to the report, “I talked to the lead detective, and he said not one witness has come forward mentioning paternity.”
